Compose toolbar can be used to add components to your elements (e.g. pictures, sounds, video, etc.). This toolbar can be found on the main toolbar (if visible) or displayed with Window : Toolbars : Compose on the main menu (you must choose File : Level : Middle or Professional for the Window item to be available on the main menu):

An alternative way of adding components to your elements is to choose from Edit : Add components menu. 

Here is the use of individual buttons:

  • Element pop-up - open the element pop-up menu with operations pertaining to the currently displayed element
  • Component pop-up - open the current component pop-up menu with operations pertaining to the current component's type

To create a text component (1) click on the text component button, (2) click on the element area at the desired location of the top-left corner of the created component, and (3) click at the location of the bottom-right corner of the created component
  • Rich text component (RTF component) - more advanced text components with different fonts, colors and formatting (those components require much more disk space and should only be used if you need to apply different fonts and formatting in text)

  • Program component - for enhancing SuperMemo with external programs and DLLs (to use this advanced component you need some programming skills)
  • Ellipse component
  • Rectangle component
  • Rounded rectangle component
  • Line component
• Component display mode buttons - change the way the components are displayed and acted upon:
  • Editing mode button - set all components in the mode that makes it possible to edit texts, edit OLE objects, etc.
  • Dragging mode button - set all components in the mode that makes both dragging and sizing possible
  • Presentation mode button - set all components in way they will be seen by the student during repetitions
• Component tags button - display component numbers, types and names
• Alignment and size button - make it possible to size and align all components that are currently in the editing or dragging modes

All component buttons listed above make it possible to add new components to the element display area. To add a component to an element you need three mouse clicks:

1. on the button corresponding to the component type of choice
2. on the top-left corner of the area where the component is to be placed
3. on the bottom-right corner of the component area

For example, to create a simple text component: click the text button, click two points over the element display area, and type in the text.
To create a simple image component: click the image button, click two points over the element, right-click the newly created image rectangle, choose Import file on the image component pop-up menu and select an image to display
To create a simple sound component: click the sound button, click two points over the element, right-click the newly created sound rectangle, choose Import file on the sound component pop-up menu and select a sound file to play
